Yes, I think this is DES's panic. Now that I have DIAGNOSTIC and INVARIANTS, I'm crashing with the following panic: panic: msleep syncing disks... 2 2 panic: runq_add: proc 0xfffffe00068257a0 (ex1) not SRUN Uptime: 23m48s dumping to dev da0b, offset 2888928 dump 125 So, I don't have a stack trace...
